Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device for connecting a vertical plate and a horizontal plate, which is used when assembling furniture for storing articles.

[0002]

[Prior art]

 Conventionally, the following devices have been known as a connecting device for a vertical plate and a horizontal plate of this type. That is, a connection is made by using a stepped screw having a threaded portion, a large diameter portion, a constricted portion, and a swollen tip end portion along the axial direction, and a screw catcher in which an engaging piece is horizontally rotatably fitted in a cylindrical case. It is a device. The stepped screw is attached to the vertical plate with the constriction and the bulge of the tip protruding horizontally, and the horizontal plate is attached with the screw catcher facing the side facing the vertical plate. Then, with the stepped screw crossing the center of the screw catcher, the screw catcher is fitted to the constricted portion and the bulging portion of the stepped screw, and then the engaging piece is rotated. As a result, the vertical plate and the horizontal plate are firmly connected to each other so that the two are brought into an engaged state without rattling.

By the way, a cutout portion having the same diameter as that of the cylindrical case of the screw catcher is formed in a portion of the horizontal plate to which the screw catcher is attached, which penetrates in the vertical direction and opens toward the vertical plate. The opening width of the notch on the vertical plate side is narrower than the diameter of the cylindrical case. On the other hand, the cylindrical case of the screw catcher has a flange part that engages with the upper surface or the lower surface of the horizontal plate on its outer peripheral surface to limit the amount of fitting, and a plurality of parts for generating frictional resistance on the inner peripheral surface of the notch. A circular rib of a book is provided. That is, the cylindrical case of the screw catcher is forcibly fitted into the notch of the horizontal plate from above or below the horizontal plate and the state is maintained.

[0004]

[Disadvantages of the prior art]

 The conventional connecting device has the following drawbacks. That is, the force fitting structure of the screw catcher with respect to the horizontal plate is such that the screw catcher is above or below the horizontal plate when the screw catcher is engaged with the stepped screw (the horizontal plate is connected to the vertical plate). It is necessary to have a strict dimensional relationship that can prevent disengagement in the direction opposite to the fitting direction. Therefore, a considerable amount of fitting force is required for mounting, which is difficult to fit. Further, when the horizontal plate is made of wood, a gap between the screw catcher and the screw catcher may occur in the cutout due to drying of the horizontal plate, and the screw catcher may come off.

[0005]

[Means for eliminating the above drawbacks]

 This invention adopts the following means in order to solve the above-mentioned drawbacks. That is, in a connecting device between a vertical plate and a horizontal plate, a stepped screw attached to the vertical plate in a state in which the constricted portion and the bulge of the tip end thereof are projected, and the vertical plate side formed on the horizontal plate and There is a screw catcher that is fitted from the vertical plate side opening in the catcher fitting receiving part that is open to at least one of the upper side and the lower side, and the screw catcher is horizontally rotatable in the case body and the case body. The engagement piece is fitted into and disengaged from the neck portion or the bulging portion of the stepped screw by rotation, and the outer peripheral surface of the case main body. The projection and the concave portion fitted to the projection have a fitting relationship between the side surface of the catcher fitting receiving portion and the side surface of the catcher fitting receiving portion.

[0006]

[Function of the device]

 This device has the following actions. This is a method in which the screw catcher is fitted horizontally from the side to the catcher fitting receiver formed on the horizontal plate, and the catcher fitting receiver and the screw catcher are mutually aligned along the horizontal direction. The protrusions and recesses that are fitted together prevent movement in the vertical direction. That is, it is possible to allow a certain amount of gap in the fitting relationship between the catcher fitting receiving portion and the screw catcher from the beginning.

The engagement piece 42 is horizontally rotatably fitted. On the outer peripheral surface of the case body 37, there is provided a projection 41 that projects in a U-shape as a whole, except for the vertical end surface portion on the side (side plate 1 side) that becomes the above-mentioned square in plan view. On the other hand, on the right and left sides of the shelf board 80, the case body 37 has a planar shape (a portion excluding the protrusion 41) so that the front portion is opened upward and the rear portion is opened downward (see FIG. 1). A catcher fitting receiving portion 85 having a corresponding shape is formed. These catcher fitting receiving portions 85 are also opened to the side facing the side plate 1 in the shelf plate 80, and the opening shape thereof is the side surface shape (all including the protrusion 41) facing the left-right direction in the case main body 37. And a recess 86 that can be fitted horizontally with the projection 41 is formed on the inner peripheral surface thereof. Therefore, the screw catcher 36 is horizontally held by being pushed horizontally toward the catcher fitting receiving portion 85 from the left or right side of the shelf plate 80. The catcher fitting receiving portion 85 may penetrate the shelf 80 in the vertical direction.

The shape of the engagement piece 42, the fitting structure in the case body 37, and the engagement / disengagement action of the engagement piece 42 with the stepped screw 35 are known, but will be described below.

[0018]

[Assembly method of article storage furniture]

 Next, a method for assembling the article storage furniture will be described. The left and right mounting members 20 are arranged at predetermined positions on the floor surface while being separated from each other by a predetermined distance, and fixed by screwing a screw or the like through the long hole 24 of the base piece 21. Similarly, the mounting member 20 is attached to the ceiling. The front treated materials 18 and 19 are passed between the front treated materials holding pieces 23 of the mounting members 20 and fixed by screwing a screw or the like from the side of the elongated hole 26. Next, the side plates 1 and 1 are brought into contact with the side plate holding pieces 21 of the mounting member 20 from both left and right sides thereof, and screws are screwed into the threaded portions 5 of the side plate 1 from the long holes 25 of the side plate holding pieces 21. At this time, it goes without saying that the height of the side plate 1 is adjusted by the adjusting mechanism 10 and the tensioning mechanism 16. After the side plates 1 and 1 are erected, four stepped screws 35 are screwed into the screw parts 5 and 5 in the same horizontal plane of a desired height. At this point or from the beginning, the screw catcher 36 is laterally fitted to the catcher fitting receiving portion 85 of the shelf board 80, and the shelf board 80 is held by the stepped screw 35 in the procedure described above (see FIG. 12). . Since the screw portion 5 of the side plate 1 is formed by the screw socket tool 6 (see FIG. 2) made of metal or the like, even if the stepped screw 35 is frequently attached and detached, the screw portion 5 is not worn or crushed. It is unlikely to occur, and the height of the shelf board 80 can be changed many times.

In this invention, the structure in which the engagement piece 42 engages / disengages with the stepped screw 35 by rotating the engagement piece 42 of the screw catcher 36 is limited to that of the above-described embodiment. Instead, other known structures can be substituted. Further, a projection 41 is provided on the inner peripheral surface of the catcher fitting receiving portion 85 of the shelf board 80, and the projection 41 can be horizontally fitted on the outer peripheral surface of the case body 37 of the screw catcher 36. It is also possible to form 86. The shapes of the protrusions 41 and the recesses 86 can also be changed as desired.

[0020]

[Effect of device]

 The present invention has the following effects due to the above-described configuration. Since the catcher fitting receiving part of the horizontal plate and the case body of the screw catcher are fitted sideways with the projections and the recesses provided on them respectively, the screw catcher moves vertically from the horizontal plate. There's never a way out. This is maintained even when the horizontal plate is made of wood and the catcher fitting receiving part is deformed due to drying or the like. Therefore, a gap to some extent can be formed from the beginning between the catcher fitting receiving portion and the case body, and the screw catcher can be easily attached (horizontal fitting) to the horizontal plate.
